Directly contact does not occur, friction loss and surface abrasion can also be greatly reduced, oil film also has certain vibration absorption ability.Although
Under general operating mode, the occasion such as lathe, reduction box automobile is scrolled bearing substitution, but in many important events, such as generates electricity
The fields such as unit, steam turbine, rolling mill, high-speed main spindle still account for critical role.The service load that sliding bearing is born by it can divide
For bush(ing) bearing and thrust slide bearing, bush(ing) bearing is divided into common circle pad bearing, oval pad bearing, three oily leaves again
Bearing, dislocation pad bearing, Shang watt fluting bearing, uniform tilting-pad bearing and non-uniform tilting-pad bearing, and thrust bearing can divide
For the fixed pad bearing of sector, Circular Tilt-pad bearing and Sector Tilting Pad bearing etc..In general design process, sliding bearing
It is all based on what certain particular job situation was designed, but in practical engineering application, the working condition meeting of sliding bearing
Change, i.e., the design conditions of sliding bearing are probably different from operating condition, and such as naval vessel generating set is on sea level
Wave, the run stability of rotor bearing can be greatly affected, have a strong impact on the reliability of generator, and a certain special parameter
Sliding bearing can not often adapt to the operating mode of this time-varying, the bearing that physical dimension is fixed can not be according to actual working state
Adjust its running parameter.Therefore, a kind of bearings technology of variable working condition when going for of necessary exploitation, not only can be with
The stability and security of rotor-bearing system are improved, the fast development of bearings technology is also beneficial to.
The content of the invention
It is an object of the invention to provide a kind of adjustable intelligent bearing support meanss of physical dimension, the device is advantageously accounted for
Existing bush(ing) bearing may be only available for the shortcoming of particular job situation, and variable working condition lower bearing rotor system when can realize
The safe and stable operation of system.
In order to achieve the above object, the technical solution adopted by the present invention is：
The device includes the adjustable sliding bearing supporting construction of physical dimension and detecting and controlling system two parts；Its feature exists
In：The adjustable sliding bearing supporting construction of physical dimension is divided into sliding bearing and supporting construction, and support is divided into support base and support
Covered on seat, the two is mounted opposite, bearing is arranged on inside supporting construction, bearing be divided into again watt with lower watt, the two is mounted opposite,
In detecting and controlling system, horizontal displacement sensors and vertical displacement sensor are arranged near sliding bearing, with status monitoring
Controller is connected, and controller, which can control servomotor to rotate, slides up and down lower half bearing.
Bearing on watt and lower watt are arranged on inside support base, and upper watt fixation, lower watt can be inside the supporting construction on
Lower slider.
Horizontal displacement sensors and vertical displacement sensor are installed into 90 degree.
Controller can control servomotor to rotate, and servomotor drives leading screw to rotate, and leading screw drives wedge movement, wedge
Movement slide up and down lower half bearing.
In apparatus of the present invention, when the working condition of rotor changes, signal, intelligence control are gathered by displacement transducer
Device processed is analyzed the vibration signal of rotor, if the working condition of bearing is different with the state of design, or rotor shakes
When dynamic value of shaking is excessive, controller will send control signal, and control servomotor rotates the angle of a bit, then drives leading screw turn
Dynamic, leading screw drives the movement of wedge, and wedge promotes lower half bearing to slide up and down, and so adjusts rotor by changing the gap of bearing
Working condition, improve rotor-bearing system Vibration Condition.
The invention has the advantages that：
1. bearing support structure goes for the working condition of time-varying.
2. the geometric parameter of self-adjustable bearing, the working condition being optimal.
3. the stability of rotor-bearing system can be monitored in real time, if there is excessive amplitude, it is adjusted in time.
4. whole device has the advantages that feedback, the intelligent control to bearing physical dimension is realized.
Brief description of the drawings
Fig. 1 is the attachment structure schematic diagram of each part of physical dimension adjustable intelligent bearing support assembly.
1 it is support base in figure, 2 be leading screw, 3 be lid on support base, 4 be bearing on watt, 5 be lower half bearing, 6 is rotor, 7
It is high accuracy displacement sensor with 8,9 be wedge, 10 be controller, 11 is servomotor.
Embodiment
The present invention is further described below in conjunction with the accompanying drawings.
A kind of adjustable intelligent bearing support meanss of physical dimension of the present invention, the device includes the adjustable slip of physical dimension
Bearing support structure and detecting and controlling system two parts；The wherein adjustable sliding bearing supporting construction of physical dimension is divided into sliding axle
Hold and supporting construction, support is divided into support base and support is covered, and the two is mounted opposite, and bearing is arranged on inside supporting construction, bearing
Two watts be divided into again above and below, the two is mounted opposite, Shang watt fixation, and lower watt can slide up and down inside supporting construction；In detection control
